Albero a led

Here's a Christmas tree project we can get behind. The "tree" itself is made of twisted pairs of insulated copper wire. At the end of each pair a surface mount LED has been soldered between the two conductors. All of the wire limbs converge into a 4×4 matrix. One tree uses a prototyping shield and an Arduino, the other tree is just using an ATtiny2313 microprocessor. Take a look at the twinkling tree in the video after the break.

This artful creation uses one color of LEDs. We'd love to see future improvements that incorporate multiple colors, enhance the fading effects, and perhaps add some interactivity such as pulsing to an inspiring rendition of Chestnuts Roasting on and Open Fire (which, consequently, is called "The Christmas Song").
